David grew up in the small Swiss resort of Anzere and started skiing at 3 years of age, was racing by 9 and became one of Britain’s best slalom skiers. Training with the Austrian and then Swiss Team in the 1980's helped him achieve many top ten Slalom and GS results in the F.I.S. and Europa Cup circuits, as well as medals at several National and Regional Championships. After a career-ending accident in a Super-G in 1991 and some major knee surgery David developed his extreme skiing technique on descents such as the North Face of the Pigne d’Arolla, the Wildhorn and the Wildstrubel. In the summer he enjoys taking on climbing and mountaineering challenges in the Muveran Massif and continues to seek new winter and summer challenges on peaks across the Vaudoise, Valaisanne and Bernese Alps all year round. Bringing 37 years of skiing to the Team, David is proud to offer his vision, passion and experience to Radius clients.

Jon was the Director of the British Freestyle Ski Team over an eight-year period during which Britain’s Freestylers were the country’s most successful skiers, winning medals at World Championship and World Cup level. Jon brings to Radius clients the experience of coordinating training programmes for elite athletes for three Olympic Winter Games (Albertville ’92, Lillehammer ’94 and Nagano ’98). He now lives in Villars in the Vaudoise Alps where he specializes in the physically demanding discipline of “ski randonnée” (ski touring). Jon’s goal is to bring his significant ski sport organizational skill and passion for off-piste adventure together to offer Radius clients the experience of a lifetime.
